A nurse is admitting an infant who has severe dehydration from acute gastroenteritis. Which of the following findings should the nurse expect?

13% weight loss.

Bulging anterior fontanel.

Bradypnea.

Capillary refill 3 seconds.

Answer and Explanation

The Correct Answer is A

The correct answer is Choice A.

Choice A rationale

A 13% weight loss indicates severe dehydration. Dehydration is classified based on the percentage of body weight lost, with severe dehydration being more than 10%6.

Choice B rationale

A bulging anterior fontanel is a sign of increased intracranial pressure, not dehydration. In dehydration, the fontanel is typically sunken due to fluid loss.

Choice C rationale

Bradypnea, or slow breathing, is not a common sign of dehydration. Dehydration often leads to tachypnea, or rapid breathing, as the body tries to compensate for fluid loss.

Choice D rationale

A capillary refill time of 3 seconds is within normal limits. In severe dehydration, capillary refill time is usually prolonged, indicating poor perfusion.

Correct Answer is A

Explanation

The correct answer is Choice A.

Choice A rationale

Placing the child in a knee-chest position helps increase systemic vascular resistance, which reduces the right-to-left shunt and improves oxygenation during a cyanotic spell in children with Tetralogy of Fallot.

Choice B rationale

Having the child lie supine with the head turned to one side does not help in managing a cyanotic spell and may not improve oxygenation.

Choice C rationale

Lying prone does not specifically address the cyanotic spell and may not be the most effective position for improving oxygenation.

Choice D rationale

Placing the child in a semi-Fowler’s position in an infant seat does not specifically address the cyanotic spell and may not be the most effective position for improving oxygenation.

Correct Answer is ["20"]

Explanation

Step 1 is: Calculate the amount of erythromycin ethylsuccinate needed. 800 mg ÷ (200 mg ÷ 5 mL) = 800 mg ÷ 40 mg/mL = 20 mL.

The nurse should administer 20 mL.
